Do not think that one or two books are enough for the salvation of the soul. The bee does not collect honey from a single flower. This is also the case of the person who reads the books of the holy fathers. One talks about faith, another about silence and prayer, other about obedience, humbleness and patience and another one about the love of God and our neighbour. Therefore, many books teach a person how to live according to the Gospel.
